This inventionvrelates to separable fastener stringers. Moreparticularly, the invention deals with a novel end construction for thetapes of the stringers and the method of producing the same to provide asimple, strong, as well as neatly finished end on the stringer tapes anda method which will materially simplify the production of fastener tapeshaving the separator ends thereon in producing what is generallyreferred to as detachable fasteners where the two stringers arecompletely separated from each other as in jacket and similarinstallations of fasteners of this kind.

The novel features of the invention will be best understood from thefollowing description, when taken together with the accompanyingdrawing, in which certain embodiments oi the invention are disclosedand, in which, the separate parts are designated by suitable referencecharacters in each of the views and, in which:

Fig. 1 is aside view of one end portion of a fastener showing the boxpart of a separator thereon.

Fig. 2 is a section on the line 2-2 of Fig. 1.

Fig. 3 is a section on the line 3-3 of Fig. 1.

Fig. 4 is a diagrammatic view illustrating the method of attachingindustrial tape to stringer ends and in severing the tape to form thereinfgrced tape mountings on said stringer ends; an

Fig. 5 is a view similar to Fig. 4 showing only a part of theconstruction and illustrating a different arrangement of stringers inthe attachment of industrial tape to the ends thereof.

In fasteners of the type and kind under consideration and, particularly,where what are known as separators are mounted on the stringer ends,such as pin and box parts employed to couple the stringer ends,dificulty has been experienced in forming a finished end on the stringertape. One method of procedure has consisted of folding the tape endbackwardly upon itself and then attaching the pin and box parts to thefolded tape at the beaded edge,

To simplify this procedure, I employ a, simple method of securing whatis commonly referred to as industrial tape, one type of which isgenerally known as Texcel, to a short-cut end of a stringer prior to theattachment of pin and box parts of a separator or any other end stopconstruction or coupling to the stringer. The industrial or finishingtape is preferably folded over the outer end of the stringer tape toform a neat and finished end on the stringer tape, as well as to sealthe cut end against unravelling.

Industrial tapes of the type and kind under consideration can be made incolors similar to or in harmonywith the colors employed on the stringertape, so that the characteristics of the industrial tape becomesubstantially invisible aside from the difference in texture which mayprevail in this tape as compared with the stringer tape. I

In Fig, 1 of the drawing, I have shown at It] the tape of one stringerof a pair of fastener stringers, on the beaded edge H of which areattached scoops l2, as in other devices of this kind. The scoops l2terminate short of thetape ends as clearly seen in Fig. 1 for attachmentof the tapes to garments to provide the mounting of end stops thereon orfor attachment of the parts of what are known as separators, forexample, the box part 63 shown attached to the beaded edge H beyond thescoops l2. Box and pin couplings are well known in the art and, for thisreason, only one stringer is shown, namely the stringer to which the boxpart i3 is attached. It will be understood, however, that the companionstringer, to which the pin part is attached, will be constructed in thesame manner, as more clearly hereinafter described.

Prior to attachment of the box part l3 to the stringer tape Hi or thebeaded edge ii thereof, the protruding end portion M of the tape has areinforcing and finishing strip or tape id attached thereto. The stripis in the form of a wide band folded centrally, as seen at 55, note Fig.3, over the outer end of the tape it or the end portion il thereof andthen extending onto and secured to opposite sides of the tape i informing side portions ll and it, as clearly shown in Fig. 3 of thedrawing. The reinforcing strip sides I! and 88 extend over the bead Hand around the outer surfaces of the bead, as seen at it) and 20.Furthermore, the strip sides l1 and 18 also extend slightly over theother edge 2|, as indicated at 22 and 23 in Fig. 2 of the drawing.

The reinforcing and finishing strip I5 is generally known as industrialtape, one brand of which being identified as Texcel. However, any typeand kind of tape of this kind can be used so long as it has propertiesto establish an adhesion to the stringer tape, at least sufliciently tomaintain the assemblage and attachment to a support or until end stopsor couplings, such as the coupling I3, has been attached thereto.

It is preferred that the type of adhesive emof a separator, which is thetape. In the present construction, it will also envelope the reinforcingtape which is disposed on the beaded edge II. In Figs. 1 and 2, the boxpart i3 is in the form of a die casting-which can be formed directlyupon the beaded edge in the manner'clearly illustrated in section inFig. 2.

In producing stringers of the type and kindunder consideration, I canfollow one of two different procedures with respect to arrangement ofstringers in attachment of the reinforcing strip or tape I thereto, i.e., with the stringer tapes arranged edge to edge with the scoopsextending in common directions from adjacent tapes, as shown in Fig. 4,or with pairs of stringer tapes coupled together and outer edges of thetapes of adjacent pairs in abutting relation to each other, asillustrated in Fig. 5.

The method of procedure in attachment of the strip I5 will be the samein-Figs. 4 and 5. However, this method is diagrammatically illustratedin Fig. 4. It comprises folding a relatively wide strip !5' from a roll24 of industrial tape, as indicated at 25, to' extend over opposed sidesurfaces of a plurality of stringer tapes which, for illustrativepurposes, are shown at illa, I01), I00 and ltd, one tape IDe being shownprior to insertion between the folds 25 of the strip IS.

The scoops of the stringer tapes Ina-Hie are all arranged at the rightside of the tapes in bringing said tapes into close proximity to eachother with the edges 2! spaced slightly from the beads H of adjacenttapes. The assemblages, as shown, are then passed between an opposedpair of rollers. one roller of the pair being shown at 25 in Fig. 4 ofthe drawing and these rollers firmly press the strip or the sideportions thereof, upon opposed sides of the stringer tapes and aroundthe beads H, producing on the resulting fastener the sides I! and I8. Alarge number of stringers may be united with the 2,4sac15 15" on thelines 29 :and 30"a-nd also necessitates a single cut 3| between outeredge portions 2! of adjacent pairs of stringers. The result, however,will produce finishing tapes l5, similar to those illustrated in Figs.1-3 inclusive.

It will be understood that, in carrying out the method, the stringertape ends are cut to apredetermined length beyond the end scoops-andthese out ends are'arranged in alinement in the application of thefinishing and reinforcing tape thereto. In referring to industrial tapesas illustrating one type and kind of tape that can be used, other tapesmore commonly referred to as heat sealing tapes can, be used and one-ofthese tapes is identified as Bondex. Still further, what is known aspressure sealing tapes can also be used. i

In connection with the method shown in Fig. 5,

it will be apparent that, in some instances, and

with some types and kinds of stringers, the severing of the strip ortape 15" between the tapes of each pair, as at 29 and 30, need not beperformed, particularly-when it is practical to use the finishing stripas a joining strip for the tape folded strip I5 and then, at apredetermined point or station spaced with respect to the rollers 26,the strip I5 is cut by a suitable cutter 21 at the sections 28 betweenthe edges 2| and the beads ii and preferably centrally of these sectionsso as to leave the protruding ends, which result in extension of thetape sides I! and i8 around the bead, as seen at [9 and 20, and over theedge 2|, as seen at 22 or 23.

In the pressing operation, through the medium of the rollers 26 orimmediately thereafter, heat may be applied particularly with some typesand kinds of tapes. However, with other tapes, the need of heat is notessential. It will also be apparent that, in the assemblage of thestringer tapes, as shown in Fig. 4, the tape edges 2! will be disposedat one side of the scoops l2. However, beyond the end scoops, the ends!4 will be substantially in alinement with each other.

In Fig. 5 of the drawing, the method as disclosed in Fig. 4, is followedin substantially the same manner-with the exception that pairs ofstringers, such for example, as the pair If, log and the pairs Illh andI02 are joined together by coupling of the scoops, prior to attachmentof the strip l5" thereto. This construction'provides wider sections 28between the stringers of=each pair which necessitates two cuttings ofthe strip ends as and when it would-be practical to do' this in makinginstallations of the fasteners in Y predetermined uses. In thisconnection, it will be apparent that other means, in addition to thestrip' l5, may be employed, for example such as an end stop constructionor reinforcement die castor otherwise applied to the beaded edgeportions or to the tape ends themselves.
